Figs. 8 and 9 are two plans of one of the:

clamps, containing the mechanism for wiping the upper over the heel and toe of the last, the cover-plate being removed to show the internal arrangement of the parts.

In a recess in the body 21 0f the clamp two i bars 28 and 29 are fitted :to slide one over the other in the longitudinal direction of the last. A lever 30, pivoted to the heel-clamp at 31, is 3 connected with the lower slide 28 by a pin on the lever engaging with the slide in such aimanner that when the lever is moved in the direction indicated by the arrow in Fig. 8 the slide 28 is moved longitudinally toward the; center of the machine, and Vice versa. Links 5 2 are jointed at one end to the rear end of? the slide 28, the other ends of these links being jointed to two curved slides or arms g, The links '32 are also connected byitwo other% links 34 to the bar 29, .to the forward end of 1 which bar a pair of folding plates or wipers I 35 are pivoted.

sponding curved arm 33. is moved in the direction indicated by the ar- These folding plates areeach 5 provided with a slot 36, in which works a pin projecting from the under side of the :corre- \Vhen the lever 30 row in Fig. 8, the slide 28 is pushed forward 5 will also be moved forward by the connectinglin'ks 32 and 34, so that the plates 35 are not only caused to move toward one another on their pivot, but are also pushed bodily forward from the position indicated in Fig. 8 to that indicated in Fig. 9, and thereby wipe the projecting edgcof the upper-leather over the edge of the last, the said turned-over edge of the upper being then secured to the insole in theordinary manner. Owing to this double or compound action of the folding plates r wipers 35, the upper is drawn regularly over the end of the last.

The'heel-clamp or head 21, as clearly shown in the enlarged views, Figs. 3 and 4, is hinged at 37 to a piece 38, so as to be capable of being inclined in a lateral direction to suit any lateral inclination of the heel of the last, and the piece 38 is centered at 39 to lug 40, so as to be capable of tilting or of being inclined in a longitudinal direction by means of the screws 38 to enable the wiper-plates in the head to be brought into position to properly act on the upper whatever the shapeor spring of the last may be. The lugs 40 are formed on the frame 41, which slides longitudinally in guides 42 in the frame 43, the latter frame being fitted to. slide vertically in guide 44 on the main frame of the machines The vertical adjustment of the clamp 21 is effected by means of the screw 45, provided with a hand-wheel 46 and Working in a nut at 47 in the frame 43. This clamp is maintained in its vertically-adjusted position by means of set-screws 4S, and in addition to its justed longitudinally, as hereinbefore de' scribed, by means of the screw-23. This screw works in a nut 49, supported between vertical guides in the frame 41, as shown in Figs.

' 3 and 10, so as to be capable of moving the said frame 41 longitudinally without interfering with its vertical movements.

The internal arrangement of the toe-clamp or head 22 is the same as that of the-heelclamp 21, so that the description of the internal mechanism of the one is .snliicient to explain that of the other. The toe-cla-n1p,however, is not supported in the same'way as the heel-clamp, but is hinged, as shown at 50, Figs. 1, 11, and 12, to the slide or frame 51, so as to be capable of being adjusted in a more or less inclined posit-ion by means of adjusting-screws 52, Figs. 1 and '2.

The longitudinal adjustment of the clamp 22 is effected by means of the screw-shaft 24,

which works in a nutor internal screw-thread formed in the slide 51 and receives its motion from the wheel 25 through the gearing 26 and spindles 27, so that by turning this screw 24 the slide 51, together with the clamp 22, will be moved in the direction of the length 7 of the table simultaneously with the clamp 21.

The vertical adjustment of the toe-clamp or head 22 is effected by the screw 77 working in a nut or screw-thread at 78 in the sliding block 79, the end of the screw 7.7 bearing against or being connected to the frame 51. (See Figs. 1, 11, and 12.) The clamp or head 22 is hinged at 50 to the frame 51, so as to permit of it being tilted or inclined in a longitudinal direction by the adjusting-screws 52 to bring the wiper-plates into position to suit the dip of the toe of the last to properly effect the wiping of the upper over the toe of the last. It will thus be seen that the heel and toe clamps or heads may be adjusted to any desired position vertically and angular] y to suit any form of last, so as to insure the proper action of the Wiper-plates on the upper being lasted. Supported by two lugs on the top or covering plate of the clamp 22 is a bolt or pin 53, upon which is fitted to slide a slotted piece or link 54 to the front 'end of which link is connected at presser 55, the construction of which is shown more clearly in Figs. 13 and 14. This presser consists of a hollow cylindrical piece 56, slotted at its upper end where it is provided with a cam-lever 57. Inside this piece 56 is fitted to slide a rod 58, provided at its lower end with a disk 59, which when in operation is pressed down by the action of the cam 57 onto the insole placed on the last. The piece 56 is provided with an external screw-thread, on which two nuts 60 and 61 are screwed and between.

which nuts is engaged one end of the slotted piece 54. Aplate 62 is fitted to slide up and down the lower end of the piece 56, but without rotating thereon. This plate is held down in its normal position (indicated in Fig. 13) by a spring 63 and is prevented from slipping off the end of the piece 56 by a projecting rim or flange, as shown in the drawing. A horseshoe-shaped or curved piece 64, provided with pin-points or projections 5, is connected by bolts or pins 65 and helical springs 66 to the plate 62, and is maintained at acertain distance therefrom by the springs 66 On the cover-plate of the clamp 22 is centered a lever 67, provided at one end with a wedge-shaped projection, which (when the presser is turned into the position shown in Fig. 1) may, by turning thelever 67, be forced beneath the outer end of the slotted piece 54, and thereby press the plate 64 onto the projecting edge of the upper and hold it securely between the points 5 on the said plate and the upper surface of the folding-over plates or wipers 35 of the clamp 22, the springs 66 permitting of the plate 64 accommodat' ing itself to any inequalities in the thickness of the leather. By turning the cam 57 the disk 59 on the lower end of the rod 58 is pressed down onto the insole, the pressure thereby exerted forcing the last and the sup.

port 2 down against the resisting-power of the spring 12, arranged beneath the bar 10, hereinbefore described, and consequently drawing the upper (which is still retained between the plates 64 and 35) tightly above the edge of the toe of the last in readiness for the plates 35 to wipe or draw the said projecting edge over the said too. To eiteet this wiping or folding-over of the upper, lever 67 Figs. 1 and 2, is turned so as to cause the plates 35 of the toe-clam p to advance, and simultaneously with the movement of the lever 67 the pressure of the disk 59 is removed from the last by turning the lever 57, and lever 67 is turned so as to withdraw the-wedge piece from beneath the slotted piece 54, and the presser may then be turned on the pin 53 into the position shown by dotted lines in Fig. 1, and the wiping-over of the upper at the toe completed by the continued motion of the lever 67*. At the front end of the clamp 22 there are pieces 109, Fig. 15, capable of being slid in guides by means of screws 110 and provided at their front ends with pivoted pieces or cheeks l11,which,whieh when thelast with the upper thereon is placed in the machine, press the upper firml y against the last and also adjust the position laterally of the toe of the last.

The distance to which the wiper-plates are permitted to press over the toe of the last may be regulated by an adjustable stop 68, attached to the edge of the clamp or head by the screw 69, and provided with a screw 70, which for fine adjustment of the motion of the wiper-plates may be made to project more or less, as required. The lever 67 ,by which. the wiper-plates are operated, is brought into contact with the end of the screw 70 when projecting the plates 35 over the last.

The grips or nipper-wipers which wipe the leather over the sides of the last are illustrated in Figs. 1, 2, 5, and 6, and in detached view, drawn to a largerscale, in Fig. 7. Each consists of a lever 71, a spring 72, and two jaws 73 and 74, thejaw 73 sliding in a guide on a jaw 74. The jaw74 is connected at 75 to the slide 76, so as to be capable of turning horizontally thereon. It is also capable of turning in a vertical direction on a horizontal axis to admit of the jaws engaging the upper. The lever 71 is pivoted at 78 on the jaw 74 and is also connected by the spring 72 to the jaw 73. -The front end of the jaw 731s bent at right angles or provided with a lip which acts against the end of the jaw 74. lVhen the lever 71 is raised into the position shown by dotted lines on the right-hand side of Fig. 5, the jaws separate, the jaw 73 moving in a direction parallel to the jaw 74, and when the said lever is turned downinto the position shown by full lines the jaws are brought close together, so as to grip the leather placed between them. The. slide 76, carrying the jaws 7 3 and 74, is capable of sliding in a direction transverse to the longitudinal axis of the last in guides provided in ablock 80, which is pivoted at 81 to the block 82*. The block'82 as shown in Fig. 7, is provided with a halfnut 7 9, engaging the screw thread on the shaft 27, the said shaft being provided with a right-hand and a left-hand thread, so that when the two spindles 27 on the opposite sides of the last are rotated, which is effected through the gearing 26 when adjusting the heads 2land 22, the nipper-Wipers will be simultaneously moved inthe direction of the axis of the last nearer to or farther from each other to suit different lengths of lasts. The slides 76 are connected in pairs by rods 83 to the opposite ends of plates or bars 84, (see Fig. 2,) the latter being pivoted to other bars or plates 85, carried on the upper ends of levers S6, fulcrumed at 37 on the frame of the machine, as shown in Figs. 1 and 5. The lower ends of the levers 86 are operated by cams 90 on 'a shaft 91, driven by gearing92 93 from a shaft 94 by means of a hand-wheel 95. WVhen the lower ends of the levers 86 are pushed outward by the cams 90, the upper ends thereof, together with the levers 84 and 85, are moved inwardthat is to say, toward the longitudinal axis of the last-so that all the nipper-wipers connected thereto are simultaneously moved in the same direction,and it will be understood that if one of the nipper-wipers come into position to act before the other nipper-wiper,

which is connected to the same plate or bar 84, the latter, owing to its peculiar connection with the said plate, will continue to move on- .ward until it likewise comes into position to act. It will be seen, also, that owing to the connection of the plates or bars 84 with the .bars 85, as shown in Fig. 2, when the nipper g last.

The two cams 90,'w-hich operate the levers 86 on opposite sides of the machine, are

so shaped and .arranged relatively to one another that the two levers 86 move inward and outward simultaneously.

lnipper-wipers on one side of the last have; been brought up to the last, and thus pre-l Vented from moving any farther in that direction before the nipper-wipers on the opposite side of the last have completed their 1110- tion, said shaft 91 is capable of sliding longitudinally in its bearings to a limited extent,

so as to complete the motion of the said nipf per-wipers.

By this arrangement if the shaft 9-1 be rotated the nipper-wipers on both sides of the machine will be moved toward the cen- I ter of the last, and assuming, for example, f that those on the right-hand side of Fig. 5 ar- I rive at the position .of rest before those on the opposite side the lever 86, connected to the former, is prevented from moving any farther in this direction, andas the cam-shaft 91 continues to rotate the now stationary lever, acting on the incline of its cam 90, causes the shaft 91 to slide longitudinally in itsbearings toward the left hand. This has the effect of causing the lever and the corresponding nipper-wipers on the left-hand side of the machine to advance at an accelerated rate toward the last. By these means, notwithstanding that both levers 86 are directly connected to one driving-shaft, the said shaft may be driven at a regular and constant speed and continues to act upon one lever, while the other lever remains stationary.

An arrangement of plates, rods,,or levers similar .to that described for adjusting the horizontal position of the nipper-wipers is employed for regulating the vertical position of the said nipper-wipers,.as shown in Figs. 5 and 6. Plates 942 are fitted to slide vertically inguides 95? on the inner sides of the frame of the machine. and to the upper end of each plate 94* is pivotedv at 96, Fig. 6, a plate or bar 97, to the opposite ends of which bar are similarly pivoted two other plates or The two plates 9P are connected to a transverse bar 100, which is connected by a rod 101 to a foot-lever or trcadle 102, by which the blocks 80 and side nipperwipers may be raised or lowered, as required. By reason of the jointed connection of the parts with one another, as described and shown, the several nipper-wipers are enabled to adjust themselves relatively to one another onopposite sides of the last as well as the varying curves of the last, and thus the pressure is equalized throughout. The blocks 80 or some of them are provided with means for adjusting them inheight relatively to the slides 82, so as to conform to the line of the last. For this purpose, as shown in Fig. 7, a tapped hole is provided through the block 80, in which Works a screw 103 the end of which bears'upon the upper surface of the block 82 so that by turning this screw the block 80 may be raised To admit of the shaft 91 rotating after the J or lowered, as required, a hole being provided through the slide 76, through which the instrument is passed to turn the screw 103.

The nipper-wiper blocks at 82 on each side of the last are each provided with half- .nuts working on right and left handed screws on shafts 27, so that by rotating the shafts the said slides may be made to approach nearer to or forced farther apart from each other, while the slides 82 have no motion in thelongitudinal direction of the last, and the slides 82* which, being connected by pieces 103 Figs. 1 and 2, to the slide of the toe-clamp 22, partake of the movements of the said clamp.

In order to insure the proper draft on the upper being lasted, I provide the nipperwiper blocks 80 or some of them with adjustable stops for the purpose of causing some of the said nipper-wipers to cease pulling on the upper, while the other nipper-wipers not thus stopped are permitted to continue pulling in the direction to insure the proper draft.

The means which I have shown in my draw ingsfor effecting this object consists in at tachiug to the block 80 aprojecting bracket 10 1, Fig. 7, fitted with a screw 105, the end of which screw, when the block 80 is raised, as hereinbefore described, will come into contact with the block 82 sooner or later, according to the extent to which the screw projects from the bracket 10.

The action of the machine is as follows: The last, with the insole and upper thereon, is placed on the supports 1 and 2, and the heel and toe clamps 21 and 22 are then brought up to the last by turning the hand-wheel 25, so that the projecting slide 29 of the heel-clamp 21 overlaps the heel of the last. The swiveling cheeks 111, carried at the front end of the toe-clamp 22, are then brought into contact with the sides of the toe of the last by turning the screws so as to adjust the last in its true lateral position. The presser 55 is then turned from theposition shown by dotted lines in Fig. 1 to that shown by full lines in Figs. 1 and 2, and the lever 67 is then turned on its center, so as to bring the wedge-shaped projection ICC IIC

on the end of the said leverbeneath the slotted piece 54, thereby forcing the curved plate 64 down onto the edge of the upper, so as to securely hold the same between the said plate and the wiper-plates 35 of the clamp 22. pro ecting edge of the upper on each side of the last is then clamped between the jaws 73 74 of the side nipper-wipers, and the adjustable stops 103 and 105 having been properly adjusted the foot of the operator is placed on the treadle 102, so as to elevate the said side wipers, some of the said nipper-wipers ceasing to pull by reason of the stops 105 coming against the blocks 82 or 82 while the other n1pper-wipers not thus stopped continue to pull on the upper toward the toe of the last or in the direction to produce the proper draft. The wheel 95 is next rotated, so as to cause the nipper-wipers on opposite sides of the last to advance toward the longitudinal axis thereof, the said nipper-wipers adjusting themselves to the varying curves of the said last, as hereinbefore described. Thelever 16 is next moved outward, so as to cause the cam 14: to elevate the supports 1 and 2 to the desired extent, after which the lever 57 is turned from the position shown by full lines in Fig. 1 into the position shown by dotted lines, thereby forcing the disk 59 down onto the last, the pressure being such as to force the last into the upper held between the plates [34 and 35 and thejaws 73 74 of nipper-wipers against the power of the spring 12, placed beneaththe bar 10, carrying the toe-support 1, the pins or projections 5 on the plate 64 still engaging the upper. The lever 67 is next turned so as to cause the wiper-plates 35 to advance slightly over the toe of the last and at the same time the lever 67 is turned back to its former position, so as to release the presser and disengage the points or projections 5 from the upper, the said presser being then turned back into the position shown by dotted lines in Fig. 1 to admit of the forward movement by the lever 67 of the wiper-plates 35, which as they advance draw the upper smoothly over the toe of the last, ready for fixing. The extent of forward motion of the lever 67 beinglimited by the-adj ustable stop 68, so as to limit the distance to which the wiper-plates 35 shall pass over the toe of the last, the side nipper-wipers are prevented from receding from the position to which they are brought by rotating the wheel 95 by a spring detent or dog 107, engaging with the teeth of the pinion 93, by which motion is transmitted to the wipers, as shown in Fig. 6, the said dog admitting of the said wheel rotating in the direction for advancing the said nipper-wipers toward the center of the last, but preventing the said pinion from turning in the reverse direction. The upper being thus turned over the toe and sides of the last, the heel portion of the said upper is next drawn or wiped over the heel of the last by turning the lever 30 so as to cause the wiperplates 35 in the clamp 21 to advance in a simi- The lar manner to that described with reference to the toe-clamp 22, and while the parts are in the position described the upper is secured to the insole by tacks or otherwise, after which the side nipper-wipers are opened out to release the. upper and the other parts of the machine are returned to their former positions, and thelast, with-the upper thereon, removed in readiness for the reception of another last.

To admit of the side nipper-wipers being withdrawn f rom the last, the lever 16 is moved inward, so as to cause a pro ection113 thereon to press on the tail of the detent or dog 107,

and thereby disengage the said detent from the pinion 92. v r I I have herein shown and described nipperwiper jaws of peculiar construction,and have also shown and described devices whereby the nipper-wipers maybe operated in such manner that some of them are enabled to cease pulling upon the upper, while others continue to pull thereon until the strain is equalized.
